Let DE, the height of mount Everest be x.
The center of the earth (point C), the horizont vanishing point (point H) and the top of mount Everest (point E) form a right triangle, where:
the hypothenuse is |EC|=|ED|+|DC|=x+4000 (DC is a radius)
|HC|=4000 mi
|HE|=210 mi
by the Pythagorean theorem:


taking the square roots of both sides we get:

so x=-4000+4005.5087 miles = 5.5087 miles
or x= -4000-4005.5 which is negative so not a solution to our problem
Answer: 5.5087 miles
Answer:
a: Neither; b: Complementary
Step-by-step explanation:
Complementary= 90 degrees
Supplementary= 180 degrees
For letter a. the answer is neither because 85 +90= 175 degrees, not 90 or 180 degrees.
For letter b. the answer is complementary because 75 +15= 90 degrees.
6.75*5=33.75
39.50-33.75
5.75/0.25
Answer 23
Answer:
Q1) 210
Q2) 198
Q6) 2.5 × base
Step-by-step explanation:
Q1) 9×(6+5+7) + 2(½×6×8)
= 162 + 48
= 210 cm²
Q2) (4+4+2+2+2+2+3+3) × 3²
= 22 × 9
= 198 ft²
Q6) parallel to base is a triangle
½ × 5 × base
= 2.5 × base cm²
